VOLUME 61: Why Is UV Protection on Prescription Glasses Important?

Most people don’t think twice about stepping into the sun. It feels harmless — even good for you. But while you’re out for a walk or sitting near a bright window, your eyes are quietly soaking up UV light. You’d never skip sunscreen on a sunny day, but eye protection often gets overlooked.

If your glasses aren’t made to block UV rays, that exposure builds up over time. And you don’t need harsh sun to be at risk — UV passes through clouds and glass. The right lenses don’t just help you see clearly; they protect the long-term health of your eyes.

What does UV exposure do to your eyes?

You won’t feel the damage happening. That’s what makes it risky. UV light can wear down parts of the eye slowly, leading to permanent problems down the track. Long-term exposure can contribute to:

• Cataracts, which cloud the lens and cause blurry vision
• Macular degeneration affects central focus and clarity
• Pterygium, a tissue growth that forms on the eye surface
• Skin cancer on the eyelids and surrounding areas

Wearing a hat or sticking to shaded areas can cut down some of the sun’s impact on your eyes. UV bounces off roads, water, and even snow. A short drive or daily walk in daylight still counts. Wearing a hat and staying in the shade helps — but glasses with UV protection offer consistent coverage all day.

Why doesn’t UV damage hurt?

Unlike a sunburn, you won’t feel UV rays harming your eyes. That’s why it often goes unnoticed. Some people get a gritty, dry feeling after too much sun, but it passes quickly and gets ignored. Here’s why that matters:

• UV rays pass through clouds and most windows
• Symptoms often don’t show until real damage has occurred
• Ongoing exposure without protection increases your long-term risk

You might assume your eyes are fine — but damage builds in the background. That’s why year-round protection matters, even on overcast or cooler days.

Are your lenses really blocking UV?

It’s easy to think that any glasses offer UV protection, especially if they’re tinted or feel high-quality. But not all lenses are created for safety — and some can be misleading. Here are the common misunderstandings:

• Tinted lenses may reduce glare, but not all block UV rays.
• Clear lenses aren’t automatically UV-safe unless treated or specially made.
• Lower-cost frames often leave out proper UV filtering altogether.

If you’ve already invested in prescription eyewear, double-check what they’re doing for your eye health — not just your eyesight.

What makes UV-protective lenses different?

UV-safe lenses either absorb or block harmful rays before they reach your eyes. Some are made from materials that naturally shield you, while others need added coatings. The best UV-blocking options include:

• Photochromic lenses – adapt to sunlight by darkening automatically
• Polycarbonate lenses – lightweight, impact-resistant, and offer built-in UV protection
• Clear lenses with UV coating – filter out rays without changing color

Choosing UV-protective prescription glasses is one of the most straightforward ways to protect your vision — especially if you wear them every day.

Ask your eye care provider if UV protection is included — don’t assume it’s built into every pair.

Do frames play a role in UV protection?

Yes — even with the right lenses, frame design affects how much protection you actually get. If your frames sit too far from your face or don’t offer side coverage, rays can still get in. Here’s what to look for:

• Larger lenses – help shield the skin around your eyes
• Outdoor or sport styles – usually designed for sun protection as well as comfort

Thin or minimal frames might look stylish, but they leave too much skin exposed. For full protection, pair UV-blocking lenses with a frame style that covers more of your face.

When should you update your prescription?

Even the best lenses can’t help if your prescription is outdated. Uncorrected vision leads to more eye strain, especially under bright or shifting light.

You should review your prescription:

• If you’ve been squinting or getting more frequent headaches
• If it’s been over two years since your last eye exam
• Before switching to new lenses, frames, or adding features

Modern lenses often include:

• Anti-glare coatings
• Blue light filters
• Scratch-resistant layers
• Built-in UV protection

Don’t assume your glasses have everything. Always ask what’s included — and whether your current lenses are still doing their job.

Final thoughts

You won’t spot UV damage right away — it builds slowly over time. Often, by the time changes in your vision become obvious, the damage is already done. The good news? You don’t need to overhaul your routine to protect your eyes. Stick with lenses that block UV, keep your prescription current, and wear frames that cover your eyes well. Small steps like these can make a big difference long-term.
